Good Friendship Movies/Dramas without Romance

Can someone recommend me some friendship Dramas/Movies without a romantic storyline ? ^^ I prefer J and KDramas/Movies and a happy ending would be really great xD Thanks to everyone!! 

These all the girl-friendships movie and dramas that i love!
Sunny
Age of youth
Dear my friends

School 2013
Code Blue 1 & 2
Tumbling (apparently this has a romantic subplot but I can't remember it AT ALL so it can't have been prominent)
Tokyo DOGS

I second Nobuta wo Produce, Last Friends and Gokusen. All three have A+++ friendships.

Yowakutemo Katemasu
Rookies
Tumbling
Gokusen
Dragon Zakura
Nobuta wo produce
Kisarazu Cat's eye
Suikyuu Yankees (has a little bit of romance but is not really that important, the main plot is about friendship)

Hana Kimi (2007, jdrama)
Crows Zero (Jdrama)
Bad Boys (Jdrama)
I second Gokusen, Nobuta wo Produce and My Boss my Hero

+1 Nobuta, Swing girls, Kisarazu, Kids

Linda Linda Linda
Nana
Kamikaze Grils
Hana and Alice synopsis make it sound more romantic than it actually is
Surely Someday
Stand Up
Waterboys
Nigth's tightrope deals with dark themes though
Mahoro Ekimae Bangaichi
Aogeba Toutoshi
Mondai no aru restaurant
Ping Pong

Evasive Inquiry Agency/Mixed Up Investigation Society is a wonderful friendship-based drama, and I'd also second Nobuto wa Produce. Age of Youth has marvelous friendships, but I wouldn't always call it "happy". Nodame Cantibile has some romance, but also great eclectic group of friends.
